Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

Combustion is the conversion of primary chemical energy contained in fuels into heat through the process of oxidation at high temperatures. The oxygen required for the combustion is supplied as part of the combustion air that is fed to the process. In ideal (stoichiometric) combustion the amount of oxygen supplied to the process is just sufficient to burn all combustibles completely. In real ...

During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's ...

FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epi-treatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D facilities, FTIR is applied to combustion thermodynamics and stack gas emissions; ...

PFOS is an extremely stable compound with strong carbon - fluorine bonds, and reports of its accumulation in wildlife and the environment have attracted international attention and concern, leading to the designation of PFOS as a persistent organic pollutant (POP).The persistent nature of PFOS prevents oxidative decomposition using wet chemical oxidation TOC analyzers; however, the Shimadzu ...

The Customer The Company is an exploration and production company that builds natural gas reserves through the acquisition and development of oil and gas assets across the U.S. They are one of the largest producers of natural gas in the Nation. The Process The Company uses multiple scrubbers to clean out the impurities of the natural gas that they ...

Fine chemicals are used as active ingredients or additives in the pharmaceutical and food & beverages industries, as well as in agriculture. The cracking of raw materials such as light virgin naphtha or liquefied gas results in intermediate products (ethylene, hydrogen, methane, CO2). At the end of the process chain, these can provide highly pure materials such as niacin (vitamin B3) or ...

The control of waste water treatment plants is of special importance - from an ecological as well as economic point of view. The most common water parameters for controlling and optimization are the total organic carbon (TOC), chemical oxygen demand (COD), total nitrogen bound ( ...

Since the introduction of Total Organic Carbon (TOC) Analyzers by Dow, Union Carbide and Automated Environmental Systems in thel960,s,l-5\ they have proven to be an invaluable tool in the environmental and process monitoring fields. While technologies have advanced since then, certain performance characteristics required for true process control have been notably absent. The purpose of this paper ...

Introduction The measurement of water vapor in natural gas has long been of industrial importance, and has been addressed by a variety of analytical techniques over the years. Chief among these techniques has been the quartz crystal microbalance (QCM) based analyzers. The QCM technology is still the workhorse for production and pipeline applications, and the technique is considered by most ...

For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new. In these industries, depending upon their location, companies have been installing APCS since the early 1970's. However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...

Boilers play a crucial role at industrial facilities and it is imperative that they be safely and properly maintained. Routine boiler maintenance can help prevent unplanned shutdowns and outages, increase the efficiency of the boiler and cut operating costs, and ensure that the facility is in full compliance with all laws and regulations governing boiler safety. What follows is a boiler ...

Rotary kiln for sale is the core of the whole cement production line and the technical management plays a vital role in the stable and continuous operation of rotary kiln. Here Kefan Machinery gives a summary to the possible failure and solutions in ...

Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

NG, FT and GTL Natural Gas (NG) is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. NG is colorless, shapeless, and odorless in its pure form. It is combustible, and when burned it emits lower levels of potentially harmful byproducts into the air than other fuels. NG is a mixture of hydrocarbon gases. While it ...

Overview A bread and bun bakery was faced with installing air pollution control equipment to control the volatile organic compounds (VOCs) emitted during their baking process. The local regulatory agency requires bakeries that generate over 25 tons of ethanol per year to reduce emissions by 95% by installing control devices on their ovens. The airstream that needed to be treated included ...
